Cll and Lewy Bodies Dementia! I need help with these diseases. My husband has had the lbd all along and the doctor didn’t tell me when I kept describing his symptoms. What medication for Lewy Body Dementia that won’t interfere with cll meds? He started with CLL in 2014 and I noticed the dementia symptoms around 2015. His meds have been ublituximab and ibrutinib for CLL and nothing for LBD.
